[0029] The invention relates to a swivel V-shaped T-structure bridge pier, which consists of a pile foundation, a cap, a pier arm 5 and a cover beam 6 from bottom to top. From bottom to top, the bearing platform is the lower turntable 1 and the upper turntable 3. The bottom of the upper turntable 3 is fixed with a rotating ball hinge 2. The rotating ball hinge 2 is placed in a spherically concave rotating groove set on the top surface of the lower turntable 1. The lower turntable 1 Concrete is poured on the outer side of the rotating spherical hinge 2 between the upper turntable 2 and forms a consolidation section. There are two pier arms 5, which are arranged in a "V" shape between the cap beam 6 and the cap, and the upper and lower ends of the pier arm 5 are connected with the cap beam 6 and the cap with arc chamfers. An inverted triangle gap is formed between the pier...
